I have a 95 blazer LT. For some reason after using my turn signal a few times I hear a relay going on and off. And it is my brake lights flashing. All three so its not my hazards. To make this issue stop temporarily. I ingage then disingage my hazards and it will stop for a while. My door unlock has never worked. I baught this blazer used and i know the passenger door was replaced with an identical door. It does not unlock on iether side or from the tailgate. I have always done it manually but i know have remote start and keyless so it would be nice if i could make it work. the guy i had do the keyless said its the relay. If anyone has answers or can offer suggestions i would appreciate it. thanks

 

It sounds like you have two unrelated problems. The issue with the tail lights is a somewhat common issue with the multifunction switch. I'm not exactly sure if the same fix can be used as what is commonly tried first on the 98+ trucks, but sometimes the hazard switch is all that needs to be replaced. Other times, the whole multifunction switch is faulty. Some people have had luck disassembling the multifunction switch and cleaning the contacts inside as well.

Your door lock issue sounds like a problem with the RKE module. Do the electric locks work from inside or are they affected as well?
